Tools -> Parameter VM Mapping (0BA7 and later versions only)

VM overview

LOGO! Base Module uses VM (Variable Memory) as a local data communication interface for data exchange by means of connections/data-transfer configuration.
You can use LOGO!Soft Comfort with the Ethernet connections menu command following instructions in the Tools -> Ethernet Connections (0BA7 and later versions only) section to construct the network topology.
LOGO!Soft Comofort performs data exchange process as follows:

• The server stores the required data into the VM area specified by the data connection and data transfer. This is defined as a "share" action in the following section.
  
• The client unit reads the server's VM area and then updates the corresponding local VM area in its network process step.
  
• After the local update, the circuit program in the client can use the information in the local VM originated from the Server.               

Note LOGO! 8.FS4 supports two types of connection, S7 and Modbus. LOGO! 0BA7 and LOGO! 0BA8 only supports S7 connection.

การต่อ SIMATIC HMI TP700 COMFORT กับ S7 300 CPU 315 2 dp (6es7 315-2ag10-0ab0) รุ่นเก่า

     วันนี้ได้ไปหน้างานซึ่งเป็นโรงงานเลื่อยไม้ได้ซื้อเครื่องจักรจากต่างประเทศ ใช้ PLC ยี่ห้อ Siemens รุ่น S7 300 CPU 315 2 dp เป็น CPU  รุ่นเก่าพอสมควร จึงทำให้การเชื่อมต่อกับจอ SIMATIC HMI TP700 COMFORT รุ่นใหม่ เป็นเรื่องที่จัดการยากพอสมควร

       เข้าเรื่องกันเลยนะครับ  ผมได้เขียนโปรแกรมด้วย Step V5.5+SP1 เนื่องจาก S7 300 CPU 315 2 dp ใช้ firmware 2.0 โปรแกรม TIA Protal ไม่ Support เนื่องจากใช้ firmware 2.6

ที่สำคัญอย่าลืมกำหนด Tag ใน Symbol Table ดังรูปด้านล่าง

*******  จากนั้น Download เข้าไปใน PLC  ************


ในส่วนของ SIMATIC HMI TP700 COMFORT  ให้ทำตามขั้นตอนดังนี้

1. เปิดโปรแกรม TIA  Portal V.13 สร้างโปรเจคใหม่ แล้วเพิ่มอุปกรณ์ใหม่(Add new device)

ไม่ต้องเชื่อมต่อกับ PLC ให้กดปุ่ม Finish ได้เลยครับ

2. สร้าง Connection ขึ้นมาเองตั้งชื่ออะไรก็ได้ ในตัวอย่างด้านล่าง ตั้งชื่อ Connection_1 เลือก Communication driver เป็น SIMATIC S7 300/400 และเลือก Online 

***SIMATIC HMI TP700 COMFORT  กับ S7 300 CPU 315 2 dp  เชื่อมต่อ ผ่าน MPI ***
เนื่องจากอุปกรณ์ทั้ง 2 ตั้งการเชื่อมต่อแบบ MPI เป็นค่าเริ่มต้นดังรูปด้านล่าง

รูป interface type: MPI ของ HMI

รูป interface type: MPI ของ PLC

3.สร้าง HMI tags  ให้ Address ตรงกับใน Symbol Table ดังรูปด้างล่าง อย่าลืมเลือก Connection ให้ตรงกับข้อ 2.

4.สร้างหน้าจอในส่วน Root screen

กำหนด Tag ให้ตรงกับ ข้อ 3.

5. ให้ทำการ Download เข้า HMI โดยการกดปุ่ม Download to device
